I have an input file with this general structure. I only want to extract the values step and weight from the hill blocks and put them into a output file using awk/sed/grep. Hill blocks are arranged in similar fashion throughout in the input file.

 configuration {
 step         5000
 dt 2.000000e+00
 }

colvar {
name d1
x  1.70882305580118e+01
v  0.00000000000000e+00
}
 
1.85104129628346e-02 9.71380137561312e-02 4.00538287370335e-02
1.25662994200839e-02 9.88655406140091e-02 1.41657757894898e-01

hill {
step            0
weight    1.00000000000000e-01
centers   1.23563844380284e+02
widths    1.25331413731550e+00
}
 hill {
 step          100
 weight    1.00000000000000e-01
centers   1.19065310650377e+02
widths    1.25331413731550e+00
}

Through some other answers I manage to found some help :-

 sed 's/^.*weight//' diol_colvar.colvars.state > hill.txt
 sed 's/^.*step//' diol_colvar.colvars.state > hill.txt

Sadly this is not working as I wanted.

I want my output something like this :-

  0     1.00000000000000e-01
  100   1.00000000000000e-01

Please help me sort this issue.

Thanks,
